No, it is not.

Explanation:

The equation for direct variation is y=kx. So to make sure your equation fits that you would do---

5x+2y=10
Subtract 5x from both sides of equation
2y=-5x+10
Divide both sides by 2 (isolate y)
y=#-5x/2#+5

Since this equation is not in the form of y=kx, it's not direct variation. Plus, when graphing, a direct variation equation always goes through the origin (0,0).
